Question

Find the mean, median and mode of the given data: 12, 11, 15, 13, 18, 11, 13, 12, 13.

Answer 1

Answer:

mean = 13.11

mode=13

median=13

Step-by-step explanation:

mean =( 12+11+15+13+18+11+13+12+13)/9

= 13.11

mode = 13 (highest frequency)

arranging in order

11, 11, 12, 12, 13, 13, 13, 15, 18

n=9, which is odd

so, Median = (n+1)/2 th term

= 10/2 th term

=5th term

= 13
